Man selenium is such an underrated element. Just those blue flames are cool as hell, not even mentioning its awesome chemistry, just a shame most its compounds are toxic :(
underrated like my channel 😂
@ChemicalForce Nah that’s not true
@@ChemicalForcethose of us that know, know. But yes, even after this long how you have only 150k subs blows my mind. You have the most beautiful chemistry on YouTube!
@@ChemicalForce lol that's true
@@thebogsofmordor7356 I think most people just don't understand chemistry, and don't have the patience to appreciate it
I really love when you show the synthesis of compounds in the video such as with nitrosyl perchlorate, PbCl4, Cl2O6, and any of the pyrophoric gases.
It’s interesting that silane is generally created using a source of H+ and germane is created with a source of H-. Is that because it’s hard to get germanium in a negative oxidation state to begin with?
I've wanted to see the reaction with gold for years, but there was so much more cool stuff in this. Awesome video!
As always, a great Video. Thank you for all your effort.
dude, im telling you, these videos are so good, exotic and just overall insane. Keep it up. Thank you Felix for making these awesome videos and cultivating a love for chemistry within many.
Nice video! You could try to dissolve elemental S, Se and Te in H2SeO4, they form the same coloured polycations like in H2SO4, but they are less stable in H2SeO4 due to its oxidizing properties (hot H2SeO4 oxidize them to IV oxidation state).
Cool
Amazing photography as always. It's nice to see these exotic substances up close and not die.
Amazing chemistry and excellent photography as always!
My only real practical contact with Selenium is a Selenium rectifier. As an automation technician/electrician I've had a few of these go bad on me.
The smell they give off when burned is almost puke inducing.
Another fascinating and beautifully filmed lesson in chemistry. It is criminal that you don't have more subs.
You should do a video with the Slow Mo Guys, would love to see some of the extremely fast reactions at super slow mo. since they can do over a million+ fps it would produce amazing shots.
That was quite beautiful the way those sulentic acid crystals were formed good job
The macro shots this man produced are some of the most genuinely beautiful images I’ve seen in my life
I work for a jeweler. I love how much chemistry goes into purifying recycled gold. The metals most "gold" jewelry is alloyed with is treated like slag. But it's all about creating a gold precipitate they can melt down and turn into more jewelry. It's crazy how much gold has been recycled. Some of the gold in your wedding band just might have come from some ring that was sold to a gold buyer, and, in turn, was sold to a jewelry manufacturer. My boss buys old jewelry all of the time. We remove all of the stones and send it off to a recycler. My boss then gets a cut of the gold extracted. Most gold you wear on your finger is old gold.
I'm pretty sure that gold is the most recycled metal. Literally recycled since it was plucked from rocks before the bronze age...
@@christopherleubner6633exactly. if it was easy to get gold out of the ground, there wouldn't be such a large industry focused solely on recycling gold. For every person wanting to buy a gold ring, there's someone looking to sell a gold ring. It's the circle of life. Lol
@@beefgoat80copper and tin were also extremely abundant on the surface. Your brass doorknob was a bronze sword 6000yrs ago lol
That was an action packed video. You invested a lot of time in preparing, testing, filming and editing the content. A huge thank you for your efforts. You have some sweet glassware and equipment.
Dude you are one of the best chemistry channels on this app. Only one working on such exotic reagents. Keep it up!🎉 (maybe a reaction of copper sulfate or copper selenate with different salts? e.g magnesium chloride? Maybe some metal salts have differing solubilities and color?)
I die inside a little bit every time someone calls a website an app...
@@TheBackyardChemist Feel you
Every video you make I always think, “wow this is the most beautiful chemistry video I’ve ever seen…” and then you make another video 😂❤
Love your work buddy! You rock!!!
Amazing Video. Thank you for the closed caption and segment titles!!!
Very interesting! Could you next time perform experiments with telluric acid ? And if you should have enough leisure time and a good standing with the secret service, perhaps polonium hydroxide ?
Holy! That was an incredible video. Thanks for the detailed documentation of the synthesis. All of those selenium compounds are terrifyingly toxic. I'd love to see your safety set up some time. Thanks for all the hard work!
Yes, safety tips please 😊
One of my favourite acids of all times, if not my favourite. Until now there was... one video about it on YouTube? PMC is a good channel, but so is this, and we actually get to see its famous reaction with gold! Great video!
Edit: I think very concentrated, very hot sulfuric acid can also eat at gold, though very slowly.
Piranha solution (sulfuric acid + hydrogen peroxide) can dissolve gold.
@@mokouf3 Sreetips tried that, but essentially no gold dissolved even when strongly heated.
My man has a death wish, splashing around all that hydrazine...
Such beauty! The footage, the music, the crystals, the fly, wow! Amazing production value! I thank you for sharing and I thank the YouTube algorithm for bringing me here. Love these videos!
Looks like a small wasp or ant, with the wasp waist, long antennae and 4 wings
Wow, I'm so amazed. I never even heard of selenic acid. It was also pretty cool to see the the copper selenate that looked the same as copper sulphate. I think that by mixing the copper selenate with sodium hypochlorite you might get red selenium along with copper oxide. Aldough i'm not sure. I think this was one of your best videos, keep up with the great work ! Amaizing.
You made my day with slow motion selenium acid oxidation’s of other compounds. My life is more spectacular watching this!
Very relieved the fly turned around. What a plot twist, having a totally new character just appear like that.
When you hit the sodium with the second drop of the acid you could see the angular momentum for a second. Super cool.
Recently found your channel and now I can't stop watching!
Incredible, after quite a few somewhat tame experiments, I was quite surprised when the test tube exploded from the white phosphorus -p4 is usually violent, but I wasn't expecting such a bang from so little. Awesome chemical, and a great presentation.
i swear i could watch seed recrystallizations all day. just so beautiful
Incredible video with all the close-ups and slow-mos.
wow! i haven’t any words! i’ll follow your channel.
i like the way you make video and also the particular reaction you do.
this video really showcases the beauty of pure chemistry. I've done my fair share of vacuum distillations and crystallizations and this really captured the sense of awe and wonder i felt the first time I did them in organic chemistry lab. thanks for the awesome content!
As always an impressive video!
Very nice video! I really liked the preparatory part with the distillation!
Man! The production quality is through the roof!
Your videos are always awesome! Great content and editing skills!👍
good background music choices idk how but it just is amazing and fits what you do
Great contribution to our understanding of Selenium chemistry
Awesome video like all you produce, can you use perchloric acid next and his reactions with diferrents elements🤔🤔
11:56 That random wasp deserves an Oscar
11:34 fly moment
Beyond the interesting chemistry, the photography is very good. I find the iodine here and in other of your videos to be especially interesting because its color is unusual.
Nice video! Can you record your cleanups just as NileRed does? I think it would be fun to watch some more exotic cleanups. It must be pretty challenging to clean up after using things like hydrazine and selenic acid. Also, instead of regular sugar, you should have tried using glucose because selenic acid is an oxidizing acid and glucose is a reducing sugar. I think it would have been interesting.
Yesss!
You saw the clean up in the video ... adding white phosphors and Hydrazine to the rest of the selenic acid. xD
@@DaftFaderYeah lol. The best way to clean stuff up is just blow it up, as we all know!
HCN is technically an acid and dissolves gold. Hydrogen cyanide is used in most gold-mining operations to dissolve the gold out of the ground-up ore.
Used to be called Prussic acid.
Ehhh still needs oxygen to work
Beautifully made!
Fantastic footage! Selenic acid has fascinated me since I was a kid. Any chance of moving on to tellurium?
really nice footage, thanks for making these videos
This footage is amazing, man. Great job
Who does the music in your videos? Are you friends with Ennio Morricone? The music always is perfectly inline with the action on screen, it's amazing! The dissonant strings and piano notes when the fly showed up were so spot on!
@Hydrazine1000 - 2023-07-24
I read the title of this video, and thought "Hey, but aqua regia can dissolve gold!" ... and then it hit me: aqua regia is a mixture of two acids, it's a compound chemical. It's not a (singular) acid.
Ok, crisis averted, carry on!
@kingnhonj954 - 2023-07-24
That's the exact thought I had also
@menjolno - 2023-07-24
no. aqua regia is nitrosyl chloride. It is not a acid because there is no hydrogen. It is a salt
@Hydrazine1000 - 2023-07-24
@@menjolno Uhmmm, there is nitrosyl chloride present in aqua regia, due to a chemical balance (reversible reaction) between HCl and HNO3 on one side and H20 and NOCl on the other side of the equation.
And since NOCl is gaseous, and some will outgas, it can be regarded as a decompostion product. Aqua regua is still (mostly) about 1 volume part nitric acid to 3 parts hydrochloric acid. (1:3 molar ratio to be more accurate.)
@martyc2051 - 2023-07-25
i too was thinking aqua regia, but then realized that its a compound, and neither of the 2 acids can effectively dissolve gold on an independent basis (if im wong, i do stand to be corrected of course)
@justsayin...1158 - 2023-07-25
@@Hydrazine1000 You are right, aqua regia is not just NOCl, and NOCl is a gaseous product of the reaction between HNO3 and HCl.
The ability to dissolve gold is however connected to the formation of NOCl and Chlorine radicals. The way you wrote it, it reads as if NOCl plays no part in the reactivity of aqua regia with gold, and is simply a decomposition product that gases out of solution, which you probably didn't mean to say, but I think it's important to point that out more clearly.
